Description

Technical Field

[0001] This utility model relates to the field of exploration drilling rigs, specifically to an exploration drilling rig and its power head device. Background Technology

[0002] Geological exploration refers to the investigation and research activities conducted through various means and methods to explore and detect geology, sample strata, determine the elemental content of each stratum based on the sampling results, determine its economic value, and calculate basic parameters. It is a technical means used in mineral prospecting to discover industrially significant mineral deposits, to ascertain the quality and quantity of minerals, and to plan for their exploitation and utilization. It provides mineral reserves and geological data needed for mine construction and design, and involves investigating and researching the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology. A drilling rig is a mechanical device used in exploration or mineral resource (including solid, liquid, and gaseous minerals) development to drive drilling tools underground and obtain physical geological data. Also known as an exploration drilling rig, its main function is to drive the drilling tools to break the rock at the bottom of the hole and lower or lower the drilling tools into the hole. It can be used to drill cores, ore cores, rock cuttings, gaseous samples, liquid samples, etc., to explore underground geology and mineral resources.

[0003] The power head is the core component of a drilling rig, primarily providing rotational torque to drive the drill rod and drill bit for drilling operations. The power head typically includes a hydraulic motor, transmission mechanism, clamping mechanism, and other components. It is generally rotatably mounted on the feed beam carriage. When drilling is required, the power head is rotated relative to the feed beam carriage to the drilling position and then started drilling. When coring is required, the power head is rotated relative to the feed beam carriage to the clearance position, where it no longer obstructs the drilling and coring operations can be performed. However, in actual operation, the power head is prone to wobbling or rebounding in both the drilling and clearance positions, leading to collisions with other components, affecting coring, or misalignment of the power head axis. Utility Model Content

[0004] This utility model provides an exploration drilling rig and its power head device.

[0005] Specifically, this utility model is achieved through the following technical solution:

[0006] In a first aspect, the present invention provides a power head device, including a feed beam slide and a power head body. The outer wall of the power head body is provided with a first snap-fit ​​member, and the first snap-fit ​​member has a snap-fit ​​hole. The feed beam slide is provided with a snap-fit ​​rod. When the power head body rotates relative to the feed beam slide to a first position, the snap-fit ​​rod is snapped into the snap-fit ​​hole of the first snap-fit ​​member.

[0007] The outer wall of the power head body is provided with a positioning member, and the feed beam slide is provided with a second snap-fit ​​member with a positioning hole. When the power head body rotates to the second position relative to the feed beam slide, the positioning member is snapped into the positioning hole of the second snap-fit ​​member.

[0008] In some embodiments, a locking seat is rotatably mounted on the feed beam carriage, and the locking rod is fixedly connected to the locking seat; the power head device further includes a limiting member, which is used to limit the locking seat to prevent the locking seat from rotating relative to the feed beam carriage.

[0009] In some embodiments, the limiting element includes a plunger indexing pin.

[0010] In some embodiments, the power head device further includes a first handle fixedly connected to the locking seat, the first handle being disposed perpendicular to the pivot between the locking seat and the feed beam carriage.

[0011] In some embodiments, the first latching member has a notch communicating with the latching hole, through which the latching rod enters and exits the latching hole; and / or, the outer wall of the latching rod is provided with threads, and the power head device further includes a locking cap that engages with the threads of the latching rod.

[0012] In some embodiments, a second handle is fixedly provided on the outer wall of the power head body; or, the power head device further includes a second handle fixedly connected to the first snap-fit ​​member.

[0013] In some embodiments, the outer wall of the positioning member is an arc surface; the second snap-fit ​​member includes a positioning seat and two jaws hinged to the positioning seat, the two jaws are arranged opposite to each other and the positioning hole is formed between the two jaws;

[0014] The power head device includes a drive member that drives at least one gripper to rotate; or, the power head device includes a limiting component that drives two of the grippers to rotate so that the two grippers move closer to each other.

[0015] In some embodiments, each of the two grippers is provided with a limiting piece on the side away from the positioning hole. The limiting assembly includes a return spring respectively disposed between the positioning seat and the limiting pieces of the two grippers. One end of the return spring abuts against the positioning seat and the other end abuts against the limiting piece, so as to drive the two grippers to rotate towards each other by means of the two return springs.

[0016] In some embodiments, the two grippers are hinged to the same pivot; one gripper is provided with a guide slide, and the other gripper is provided with a tooth; when the two grippers rotate relative to each other, the tooth slides along the guide slide.

[0017] In the power head device provided in this application, the first position can be the drilling position. That is, when the power head body rotates to the first position (drilling position) relative to the feed beam slide, the locking rod is engaged in the locking hole of the first locking member, so that the locking rod is fixed in the locking hole, thereby fixing the power head body in the drilling position relative to the feed beam slide. This realizes the positioning of the power head body during drilling in the first position (drilling position), preventing the power head body from loosening during drilling, thus avoiding damage to the power head positioning bearing. Furthermore, if it loosens, the axial direction of the power head drive shaft will not be coaxial with the hole axis, increasing the friction between the drill rod and the hole wall, which could cause engine overload. The second position can be the avoidance position, that is, the position where the power head body avoids the drilling. When the power head body rotates to the second position (avoidance position) relative to the feed beam slide, the positioning member is engaged in the positioning hole of the second engaging member, so that at least part of the positioning member is fixed in the positioning hole, thereby fixing the power head body in the avoidance position relative to the feed beam slide. This achieves the positioning of the power head body in the second position (avoidance position), preventing the power head body from rebounding and colliding with the core retrieval device during the core retrieval process, and ensuring the normal operation of the core retrieval.

[0018] Secondly, this utility model provides an exploration drilling rig, including a power head device as described in any of the above-mentioned embodiments. Compared with the prior art, the beneficial effects of this exploration drilling rig are the same as those of the power head device described above, and will not be repeated here.

Detailed Implementation

[0033] This disclosure will now be discussed with reference to several embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement this disclosure, and are not intended to imply any limitation on the scope of this disclosure.

[0034] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to"; the terms "embodiment" and "one embodiment" are to be interpreted as "at least one embodiment"; the term "another embodiment" is to be interpreted as "at least one other embodiment"; the terms "first," "second," etc., may refer to different or the same objects; the term "setup" is not limited to direct or indirect connections, nor to specific connection methods. Other explicit and implicit definitions may also be included below.

[0035] Specific numerical values ​​or ranges may be referred to in the following description. It should be understood that these values ​​and ranges are merely exemplary and may be helpful in putting the ideas of this disclosure into practice. However, the description of these examples is not intended to limit the scope of this disclosure in any way. These values ​​or ranges may be set differently depending on the specific application scenario and requirements.

[0036] As mentioned above, the power head is generally rotatably mounted on the feed beam slide 2. When drilling is required, the power head is rotated relative to the feed beam slide 2 to the drilling position and the power head is started to drill. When core sampling is required, the power head is rotated relative to the feed beam slide 2 to the clearance position. At this time, the power head no longer obstructs the drilling, and core sampling can be performed. However, in actual operation, the power head is prone to shaking or rebounding in both the drilling and clearance positions, leading to collisions with other components, affecting core sampling, or misalignment of the power head axis. In particular, when the drive mechanism 101 of the power head device is a hydraulic motor, the hydraulic motor is connected to multiple oil pipes and at least one water pipe. The oil and water pipes are relatively thick and rigid. When the power head body 1 is in the clearance position, it is easy for it to rebound to the drilling position under the flexibility of the oil and water pipes, colliding with the inner tube of the core sampler, resulting in the inability to perform core sampling. Furthermore, when the power head body 1 rotates to the drilling position for normal drilling, the vibration of the drilling rig during drilling can cause the power head body 1 to loosen. This loosening exacerbates the damage to the power head positioning bearing. Additionally, the misalignment of the power head drive shaft with the hole axis increases friction between the drill rod and the hole wall, potentially overloading the engine. Furthermore, the misalignment between the power head axis and the hole axis can cause problems when installing a new drill rod after drilling one, making it difficult to connect or tighten the screw. Therefore, after starting drilling, it is crucial to ensure that the power head axis and the hole axis are aligned at the same height.

[0037] In view of the above, this application provides a power head device, which includes a feed beam carriage 2 and a power head body 1. The power head body 1 is rotatably mounted on the feed beam carriage 2, and the axis of rotation of the power head body 1 relative to the feed beam carriage 2 is parallel to the axis of rotation of the drill bit of the power head body 1. Thus, the power head body 1 can rotate relative to the feed beam carriage 2 to a drilling position for drilling, and can also rotate to a clearance position to avoid the drill hole, facilitating core extraction.

[0038] The outer wall of the power head body 1 is provided with a first snap-fit ​​member 103, and the first snap-fit ​​member 103 has a snap-fit ​​hole 1031; the feed beam slide 2 is provided with a snap-fit ​​rod 205. When the power head body 1 rotates relative to the feed beam slide 2 to the first position, the snap-fit ​​rod 205 is snapped into the snap-fit ​​hole 1031 of the first snap-fit ​​member 103. In this technical solution, the first position can be the drilling position. That is, when the power head body 1 rotates to the first position (drilling position) relative to the feed beam slide 2, the locking rod 205 is locked in the locking hole 1031 of the first locking member 103, so that the locking rod 205 is fixed in the locking hole 1031, thereby fixing the power head body 1 in the drilling position relative to the feed beam slide 2. This realizes the positioning of the power head body 1 during the drilling process in the first position (drilling position), preventing the power head body 1 from loosening during the drilling process, thereby avoiding damage to the power head positioning bearing. Moreover, if it is loosened, the axial direction of the power head drive shaft will not be coaxial with the hole axis, which will increase the friction between the drill rod and the hole wall and cause the engine to be overloaded.

[0039] Furthermore, the outer wall of the power head body 1 is provided with a positioning element 105, and the feed beam slide 2 is provided with a second locking element 207 having a positioning hole. When the power head body 1 rotates relative to the feed beam slide 2 to the second position, the positioning element 105 is locked in the positioning hole of the second locking element 207. In this technical solution, the second position can be an avoidance position, that is, a position where the power head body 1 avoids drilling. That is, when the power head body 1 rotates relative to the feed beam slide 2 to the second position (avoidance position), the positioning element 105 is locked in the positioning hole of the second locking element 207, so that at least part of the positioning element 105 is fixed in the positioning hole, thereby fixing the power head body 1 in the avoidance position relative to the feed beam slide 2, realizing the positioning of the power head body 1 in the second position (avoidance position), preventing the power head body 1 from rebounding and colliding with the core retrieval device during the core retrieval process, and ensuring the normal operation of core retrieval.

[0040] like Figure 1 As shown, the power head body 1 may include components such as a drive mechanism 101 and a transmission mechanism 102, wherein the drive mechanism 101 may be a hydraulic motor, an electric motor, or other components. The transmission mechanism 102 may include transmission gears. The first latching member 103 may be disposed on the outer side of the housing of the transmission mechanism 102; the positioning member 105 may also be disposed on the outer side of the housing of the transmission mechanism 102. Of course, the first latching member 103 and the positioning member 105 may also be disposed on the outer wall of other components of the power head body 1, which is not limited here. It is understood that the drive mechanism 101 and / or the transmission mechanism 102 may be selected from any structure in the prior art that can meet the usage requirements, which is not limited here.

[0041] In some embodiments, such as Figures 1-4As shown, a locking seat 201 is rotatably mounted on the feed beam slide 2, and a locking rod 205 is fixedly connected to the locking seat 201. That is, when the locking seat 201 rotates relative to the feed beam slide 2, it drives the locking rod 205 to rotate together. The axis of rotation of the locking seat 201 relative to the feed beam slide 2 is parallel to the axis of rotation of the power head body 1 relative to the feed beam slide 2. The extension direction of the locking rod 205 can be perpendicular to the axis of rotation of the locking seat 201 relative to the feed beam slide 2. The power head device also includes a limiting member, which is used to limit the locking seat 201 to prevent it from rotating relative to the feed beam slide 2. Specifically, as... Figure 1 As shown, the locking seat 201 can be provided with a limiting groove. After the limiting member is inserted into the limiting groove, the locking seat 201 is prevented from continuing to rotate relative to the feed beam slide 2. Specifically, the locking seat 201 may include a connecting piece 203, which is eccentrically positioned. The limiting groove can be provided on the connecting piece 203 so that the limiting member inserted into the limiting groove can prevent the locking seat 201 and its connecting piece 203 from continuing to rotate.

[0042] By adopting the above technical solution, such as Figure 3 and Figure 4 As shown, when the power head body 1 rotates to the first position, it drives the locking seat 201 and the locking rod 205 to rotate relative to the feed beam slide 2, causing the locking rod 205 to engage in the locking hole 1031 of the first locking member 103. Then, the locking seat 201 is limited by the limiting member to prevent it from rotating relative to the feed beam slide 2. With this configuration, during the drilling process of the power head body 1 in the first position, the locking rod 205 restricts the movement and loosening of the first locking member 103 and the entire power head body 1, ensuring that the power head body 1 in the drilling position is fixed relative to the feed beam slide 2, preventing the power head body 1 from loosening during drilling, thereby avoiding damage to the power head positioning bearing. Furthermore, if it loosens, the axial direction of the power head drive shaft will not be coaxial with the hole axis, increasing the friction between the drill rod and the hole wall, which could cause engine overload.

[0043] In some embodiments, such as Figure 5 and Figure 6As shown, the limiting component includes a plunger indexing pin 202. Specifically, the plunger indexing pin 202 includes a pin seat 2022, a pull rod 2021, and a locking nut 2023. The pin seat 2022 is hollow, and a portion of its outer wall has external threads. The locking nut 2023 engages with the external threads of the pin seat 2022. The pull rod 2021 passes through the hollow hole of the pin seat 2022. When the lower end of the pull rod 2021 extends out of the pin seat 2022, it can extend into the limiting groove of the locking seat 201 to prevent the locking seat 201 from rotating. When the pull rod 2021 is pulled upwards, its lower end moves upwards and extends out of the limiting groove, allowing the locking seat 201 to continue rotating relative to the feed beam slide 2. Furthermore, the pin seat 2022 includes multiple clamping parts distributed circumferentially around it. These clamping parts surround the pull rod 2021, with circumferential gaps between adjacent clamping parts. The locking nut 2023 simultaneously engages with the threads on the outer surfaces of the multiple clamping parts, thereby clamping the pull rod 2021 and preventing it from moving up or down. When the pull rod 2021 needs to move up or down, the locking nut 2023 rotates until it is no longer threaded with the multiple clamping parts. At this point, the pull rod 2021 can move up and down. After the pull rod 2021 moves to a preset position, the locking nut 2023 simultaneously engages with the threads on the outer surfaces of the multiple clamping parts, thereby clamping the pull rod 2021 and preventing it from moving up or down.

[0044] In some embodiments, such as Figures 1-4 As shown, the power head device also includes a first handle 204 fixedly connected to the locking seat 201. The first handle 204 is arranged perpendicular to the pivot between the locking seat 201 and the feed beam slide 2. With this arrangement, when the locking seat 201 needs to be rotated, the first handle 204 can be directly moved, causing the locking seat 201 and the locking rod 205 to rotate together, which is more labor-saving and easier to operate. Specifically, the first handle 204 can be fixedly connected to the connecting piece 203. The first handle 204 and the locking seat 201 can be fixed by welding, interference fit, snap-fit, threaded connection, etc., or the first handle 204 and the locking seat 201 can be an integral structure.

[0045] In some embodiments, such as Figures 1-4 As shown, the first latching member 103 has a notch that connects to the latching hole 1031, through which the latching rod 205 enters and exits the latching hole 1031. Specifically, the latching hole 1031 can be a U-shaped hole. This design facilitates the entry and exit of the latching rod 205 into and out of the latching hole 1031. Of course, the latching hole 1031 can also be a round hole, a V-shaped hole, etc.

[0046] In some embodiments, such as Figure 4As shown, the outer wall of the locking rod 205 is threaded, and the power head device also includes a locking cap 206 that engages with the threaded locking rod 205. Thus, after the locking rod 205 is engaged in the locking hole 1031, the locking cap 206 can be rotated to press against the inner wall of the locking hole 1031, preventing the locking rod 205 from disengaging from the locking hole 1031. Specifically, a tapered boss can be provided on the side of the locking cap 206 near the locking hole 1031. Along the direction away from the locking hole 1031, the area of ​​the tapered boss gradually increases. With this design, when the locking cap 206 rotates to press against the inner wall of the locking hole 1031, the tapered boss tightly engages with the inner wall of the locking hole 1031, further preventing the locking rod 205 from disengaging from the locking hole 1031.

[0047] Because the power head body 1 is relatively heavy, the operation of driving it to rotate relative to the feed beam slide 2 requires significant labor intensity and is time-consuming and labor-intensive. In view of the above, a second handle 104 is fixedly provided on the outer wall of the power head body 1; or, the power head device further includes a second handle 104 fixedly connected to the first locking member 103. The extension direction of the second handle 104 forms an angle with the rotation axis of the power head body 1 relative to the feed beam slide 2. Optionally, the extension direction of the second handle 104 intersects or is perpendicular to the rotation axis of the power head body 1 relative to the feed beam slide 2. Using this technical solution, the rotation of the power head body 1 relative to the feed beam slide 2 can be achieved simply by moving the second handle 104, increasing the lever distance, reducing the labor intensity of the operator, and saving more time and effort.

[0048] The second handle 104 and the first snap-fit ​​member 103 can be fixed by welding, interference fit, snap-fit, threaded connection or other means, or the second handle 104 and the first snap-fit ​​member 103 can be an integral structure.

[0049] In some embodiments, such as Figures 7-9 As shown, the outer wall of the positioning member 105 is curved, which facilitates the movement of the curved positioning member 105 into the positioning hole. The second snap-fit ​​member 207 includes a positioning base 2073 and two grippers 2072 hinged to the positioning base 2073. The two grippers 2072 are arranged opposite to each other, and a positioning hole is formed between the two grippers 2072. A gap is formed between the clamping ends of the two grippers 2072, and the positioning member 105 can enter and exit the positioning hole through the gap between the clamping ends of the two grippers. The end faces of the clamping ends of the two grippers 2072 can form guide slopes, and the curved outer wall of the positioning member 105 gradually moves into the positioning hole along the guide slopes to prevent the positioning member 105 from being misaligned.

[0050] The two grippers 2072 can rotate relative to the positioning base 2073, so that the two grippers 2072 move closer together to clamp the positioning member 105. Since a positioning hole is formed between the two grippers 2072, the positioning member 105 is locked within the positioning hole, thereby preventing the power head body 1 in the second position from springing back. The power head device includes a drive member that drives at least one gripper 2072 to rotate. The drive member can drive the gripper 2072 to rotate so that the two grippers 2072 move closer together to clamp the positioning member 105, or the drive member can drive the gripper 2072 to rotate so that the two grippers 2072 move away from each other to release the positioning member 105. The drive member can be a telescopic cylinder, a motor, or other components. The telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder. The telescopic cylinder can be connected to the side of one gripper 2072 opposite to the other gripper 2072. The telescopic cylinder extends and retracts, causing the gripper 2072 to rotate relative to the positioning base 2073.

[0051] Alternatively, the power head device includes a limiting assembly that drives the two grippers 2072 to rotate so that the two grippers 2072 move closer to each other. The limiting assembly causes the two grippers 2072 to rotate toward each other, thereby clamping the positioning member 105 and preventing the positioning member 105 from dislodging from the positioning hole.

[0052] In some embodiments, such as Figure 9 As shown, each of the two grippers 2072 has a limiting piece 2075 on the side opposite to the positioning hole. The limiting assembly includes a return spring 2071 respectively disposed between the positioning seat 2073 and the limiting pieces of the two grippers 2072. One end of the return spring 2071 abuts against the positioning seat 2073 and the other end abuts against the limiting piece 2075, so that the two return springs 2071 drive the two grippers to rotate towards each other. The return spring 2071 can be a compression return spring 2071, and both ends of the return spring 2071 can be fixedly connected to the positioning seat 2073 and the limiting piece 2075 respectively.

[0053] Two positioning posts can be provided on the positioning base 2073 and / or the limiting piece. The end of the return spring 2071 is sleeved on the positioning post to position the return spring 2071. Using this technical solution, the return spring 2071 can be a compression return spring 2071. The elastic force of the return spring 2071 drives the two grippers 2072 to rotate towards each other, thereby clamping the positioning member 105 and preventing the positioning member 105 and the power head body 1 from rebounding during core removal. When core removal is required, the power head body 1 is driven to rotate the positioning member 105, causing it to rotate between the two grippers 2072 by inertia. After core removal is completed, the power head body 1 is driven to rotate the positioning member 105 until the power head body 1 disengages from the positioning hole.

[0054] In some embodiments, the two grippers 2072 are hinged to the same pivot axis. This configuration is simple in structure and easy to manufacture. One gripper 2072 is provided with a guide slide, and the other gripper 2072 is provided with a tooth 2074. When the two grippers 2072 rotate relative to each other, the tooth 2074 slides along the guide slide. This configuration can prevent the two grippers 2072 from misaligning or shifting during rotation, facilitating smooth rotation of the two grippers 2072. Specifically, one gripper 2072 is provided with a groove, the groove wall of which forms a guide slide, and the tooth 2074 of the other gripper 2072 slides along the groove wall.

[0055] This utility model embodiment also provides an exploration drilling rig, including the power head device as described in any of the above embodiments. Compared with the prior art, the beneficial effects of this exploration drilling rig are the same as those of the power head device described above, and will not be repeated here.
